  • Updated the version of Apache Ant included with Eggplant Performance to 1.10.12.

Features and Improvements 9.4.0 (13 Dec 2021)

  • Updated technical terminology to reflect Keysight’s values of inclusion and diversity.
  • Note: You may need to rebuild your project or workspace before running any tests. Workspaces with Web Java or Web C# Virtual User scripts that use the HostFilteringMode enum are upgraded automatically when opened with Eggplant Performance 9.4.0 or later.

  • Updated the JRE or JDK in the installer from Java 11.0.11 to 11.0.13 (CRD-1051).
  • Additional improvements and bug fixes:
    • Eggplant Functional suites that contain multiple scripts with identical names within subfolders can now be imported correctly. The subfolder name is prepended to the generated Eggplant Performance script name (CRD-1004).

    • Error message: “[Errno 22] Invalid argument in slot_testAndSeriesRequestFinished” no longer occurs when trying to run a test in an imported workspace that was previously exported with test runs excluded.
    • Error message: “'CSCLRScript' object has no attribute 'estimatedTransactionRatePerVU'“ no longer occurs when configuring a test that has multiple Virtual User groups with different scripts or workflows assigned to them (CRD-1062).

Features and Improvements 9.3.0 (27 Oct 2021)

  • Updated the version of Postgres included with Eggplant Performance Analyzer to 13.4.
  • Note: If you have an existing analysis database, you must use the installer in UI mode to install Eggplant Performance Analyzer 9.3.0. Technical limitations mean that you cannot use the unattended (command-line) installation mode to upgrade a database created with a previous version of Postgres.

  • Additional improvements and bug fixes:
    • Added an extra default generation rule to Web Virtual User types, which promotes WebSocket connection upgrade requests (CRD-612).

Features and Improvements 9.2.0 (4 Aug 2021)

  • Updated the JRE/JDK included in the installer(s) from Java 8 to Java 11 and upgraded all Eggplant Performance Java components to be compatible with Java 11.

Note: If you have been using your own Java 8 JRE/JDK, you will need to change it to a Java 11 JRE/JDK in the Studio → Tools → Preferences → Compilers and IDEs window. Otherwise, you may encounter errors similar to the following:

Exception in thread "main" java.lang.UnsupportedClassVersionError: <class> has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

    If you are running the Eggplant Performance Injector software on a Linux operating system (either to run Virtual Users or for SUT monitoring) then you will need to install a Java 11 JRE/JDK and make sure it replaces the previous Java version in the ${PATH} variable
